Abstract
The main purpose of this pilot study was to investigate the insulin sensitizing effect of glycine as a dietary supplement in insulin resistant (IR) normoglycemic subjects (N= 10), and to determine significant changes in insulin sensitivity and lipid profile after four weeks of glycine supplementation. Descriptive statistics were used to describe the basic characteristics of the study population. A paired t-test was used to determine differences between insulin sensitivity and lipid profile pre- and post- intervention, considering the estimation of HOMA-IR and Matsuda- index scores. Results showed that glycine supplementation might improve triglyceride (TG) levels in European Americans; and low-density lipoprotein cholesterol (LDL-c) concentrations in women after a four-week of intervention. Although, this work reports interesting results, these findings did not provide sufficient evidence to demonstrate that glycine supplementation may improve insulin sensitivity and lipid profile in insulin-resistant (IR) normoglycemic subjects. The implementation of a larger investigation with sufficient power is necessary to fully test our hypothesis and further explore these findings.
